Ndedzipi dziviriro dzekugadzira uye kuisirwa kweNTC tembiricha sensors dzinoshandiswa mumhepo conditioners?

I. Magadzirirwo uye Sarudzo Mafungiro

1. Temperature Range Compatibility
   • Ita shuwa kuti tembiricha yekushandisa yeNTC inovhara nharaunda ye AC system (semuenzaniso, -20°C kusvika 80°C) kudzivirira kuita kudonha kana kukuvadzwa kubva mukudarika miganhu.
2. Kururama uye Kugadzirisa
   • Sarudza ma sensors epamusoro-soro (semuenzaniso, ± 0.5 ° C kana zvirinani) kuti uwedzere kusanzwa kwekudzora tembiricha. Resolution inofanira kuenderana nezvinodiwa nehurongwa (semuenzaniso, 0.1 ° C).
3. Response Time Optimization
   • Rongedza masensa ane yakaderera yekupisa nguva isingachinjiki (semuenzaniso, τ ≤10 masekonzi) kugonesa mhinduro nekukurumidza uye kudzivirira compressor bhasikoro.
4. Packaging uye Durability
   • Shandisa epoxy resin kana girazi encapsulation kudzivirira humidity, condensation, uye makemikari corrosion. Kunze kweyuniti sensors inofanirwa kusangana neIP67 chiyero.

II. Installation Position uye Mechanical Design

1. Kusarudzwa Kwenzvimbo
   • Evaporator/Condenser Monitoring:Batanidza zvakananga kune coil pamusoro, kudzivirira yakananga kuyerera kwemhepo (semuenzaniso,> 5 cm kubva pamhepo).
   • Return Air Temperature:Isa pakati pemadhakisi ekudzoka, kure nekudziya / kutonhora.
2. Thermal Coupling
   • Chengetedza ma sensors ane girisi yekupisa kana simbi zvisimbi kuti uderedze kupisa kwekudzivirira pakati pe sensor uye nzvimbo yakanangwa.
3. Airflow Interference Mitigation
   • Wedzera nhovo dzekuyerera kwemhepo kana kushandisa probes ine shielding kuderedza mhepo yekumhanyisa mhedzisiro (yakakosha kune inotonhorera-mhepo masisitimu).

III. Circuit Design Guidelines

1. Voltage Divider Parameters
   • Match kudhonza-up resistors kune NTC's zita rekudzivirira (semuenzaniso, 10kΩ pa25°C) kuve nechokwadi chekuti ADC yekupinda voltage inowira mukati meiyo inoshanda renji (semuenzaniso, 1V–3V).
2. Linearization
   • Isa iyo Steinhart-Hart equation kana piecewise yekutarisa matafura kutsiva iyo isiri-linearity uye kunatsiridza huchokwadi.
3. Noise Immunity
   • Shandisa tambo dzakamonyoroka/dzakadzivirirwa, nzira kubva kunzvimbo dzine ruzha rukuru (semuenzaniso, compressors), uye wedzera RC yakaderera-pass mafirita (semuenzaniso, 10kΩ + 0.1μF).

   
IV. Environmental Adaptability

1. Kudzivirira Kwemvura
   • Nama ma sensors ekunze nemakomponi ekuputira uye shandisa zvibatanidza zvisingapindi mvura (semuenzaniso, M12 aviation plugs).
2. Vibration Resistance
   • Chengetedza masensa ane mamoiri anochinjika (semuenzaniso, silicone pads) kudzivirira nyaya dzekusangana kubva kucompressor vibrations.
3. Kudzivirira Dust
   • Gara uchichenesa masensa kana shandisa mavhavha ekudzivirira anobvisika (semuenzaniso, simbi mesh).

V. Calibration uye Maintenance

1. Multi-Point Calibration
   • Gadzirisa patembiricha yakakosha (semuenzaniso, 0°C musanganiswa wemvura yechando, 25°C thermal chamber, 50°C oiri yekugezera) kugadzirisa kusiyana kwebatch.
2. Yenguva Yakareba Kugadzikana Kuongorora
   • Ita calibration yemunda makore maviri ega ega kuti uone kukukurwa (semuenzaniso, kukukurwa kwepagore ≤0.1 ° C).
3. Fault Diagnostics
   • Shandisa yakavhurika/ipfupi-yedunhu kuona uye kukonzeresa chenjedzo (semuenzaniso, E1 kukanganisa kodhi) kune zvisirizvo.

VI. Kuchengeteka uye Kutevedza

1. Certifications
   • Ita shuwa kutevedzera UL, CE, uye RoHS zviyero zvekuchengetedza uye zvakatipoteredza zvinodiwa.
2. Insulation Testing
   • Simbisa tambo yekuvharisa inomira 1500V AC kweminiti imwe kudzivirira njodzi yekuparara.

Matambudziko Anowanikwa uye Mhinduro

• Nyaya:Kunonoka sensor mhinduro inokonzera compressor cycling.
  Solution:Shandisa madiki probes (pasi τ) kana optimize PID control algorithms.
• Nyaya:Condensation-induced contact failure.
  Solution:Reposition sensors kure necondensation zone kana kuisa hydrophobic coatings.

Nekugadzirisa zvinhu izvi, masensa eNTC anogona kuve nechokwadi chekushanda kwakavimbika mumasisitimu eAC, kuvandudza kushanda kwesimba (EER) uye kuwedzera hupenyu hwemidziyo.
